Starynovy, good that you said that... I did some research, and often, sensors have 20ms response time, which is waaaay to slow. I now found them with " =< 2ms" .. so I am searching for even better. Remember: at 6000 RPM, one revolution takes only 10 ms ... and what is the total delivery time of the fuel then ? For sure not more than 2 ms ...
About injectors spraying into bucket. The whole problem that I tried to explain is: The injector is set to pop at a pressure difference of 150 bar. That means line pressure of 150 bar when just spraying into bucket... but it will be 400 bar when spraying into a room with 250 bar pressure ... or 600 when there is 450 bar pressure.
That is the whole problem and the reason why I want to measure the line pressures: they for sure will be higher than 150 bar... but we do not know how high.
And if it would be for example 500 bar, I think that an injector cannot be set for such a high pressure, or can it be ?
Starynovy and R-3350, I think you are both right about controlling the SOI. Measuring a piezo pulse on the fuel line will work as a needle lift sensor signal, but the exact position of the pump shaft for sure will also be usable for a control strategy too. I think, when the time will come, we will investigate which strategy is better.
I will have a closer look to the elements development, I wanted to do it anyway
SurfRodder, thank you ... and thanks again for the very valueable tip about the pump tool. Will save me some annoying fabrication
